Watch video from the Action Cam as Philadelphia Police Capt. Sekou Kinebrew provides details on the case of a loaded gun brought to Fels High School on February 26, 2018.

The 9th grade student was immediately taken into custody, said Philadelphia Police Capt. Sekou Kinebrew.

The student admitted to police that he had stolen the gun from a car near his home sometime during the past week, Kinebrew said.

He has no disciplinary problems and no criminal record.

Police were working to determine if a rumor that the student had been beaten up and brought the weapon to school for protection is accurate.

The boy and his mother were being interviewed by police Monday afternoon.

After the weapon was found, the school was immediately put on lockdown.

A student who did not want to be identified told Action News they were kept in the auditorium.

Word quickly spread of what was going on.

"The staff didn't tell us it was a gun, but you heard it from kids," the student said.

The lockdown was lifted at 8:22 a.m.

Lillian Izzard, the Assistant Principal of Fels High School, released a letter to parents, saying, in part, "I want to assure you that we take the health and safety of our students very seriously and that we have taken the necessary steps in response to this incident. If you or your child has any concerns regarding this incident, I encourage you to please contact my office directly. Please note that the Philadelphia Police and School District Police will conduct a full investigation regarding this incident."

There were no injuries to students or staff.

"The threat was neutralized very quickly, but there was an external search and internal review to make sure everything was all safe before and the Philadelphia police are the ones who lifted the lockdown," said school district spokesman Kevin Geary.

Below is the letter in full sent from Lillian Izzard, the Assistant Principal of Fels High School, to parents:
